Elad Ashkenazi c4cc0154be LV2: Optimizations and fixes 
Fix and optimize sys_ppu_thread_yield

Fix LV2 syscalls with timeout bug. (use ppu_thread::cancel_sleep instead)

Move timeout notification out of mutex scope

Allow g_waiting timeouts to be awaked in scope

Savestates Support For PS3 Emulation (#10478) 2022-07-04 16:02:17 +03:00
Eladash 64997662d2 LV2: Fixup for IPC 
* Fix typo in lv2_obj::create.
* Always save ipc_key as 0 for non-shared object creations, regardless of thbe value set by creation attribute.
* Show IPC key of shared memory (sys_mmapper) memory objects in kernel explorer.

LV2: Improve IPC support (#10206) 
* Remove custom event queue's IPC management of favour of universal LV2 approach.
* Move ipc_manager to FXO.
* Fix ipc_manager internal storage memory leak: deallocate entry when IPC object destroyed.
* Rewrite lv2_obj::create to be simpler (remove many duplicated code).
* Always execute lv2_obj::create under both IPC and IDM mutexes at once (not in non-atomic single-steps). Fixing potential case where concurrency can cause IDM to contain 2 or more different objects with the same IPC key with SYS_SYNC_NOT_CARE (instead of the same object).
* Do not rely on smart ptr reference count to tell if the object exists. Use similar approach as event queues as it makes error checkings accurate.
* Optimize lv2_event_port by using std::shared_ptr for queue which wasn't allowed before.

Eladash f43260bd58
Atomic waiting refactoring (#9208) 
* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
